Devetashka Pestera is not only the largest cave in Bulgaria but also
in the Balkans Peninsula. It is situated about 25 km (15.5 miles) northeast
of the town of Lovec. There are five openings at the cave entrance. The largest
opening is estimated at about 180 ft wide by 60 feet high. There is a single
story concrete building under the bridge. This can be seen as two white spots
at the bottom left of the rear span, providing some sense of scale. Photo
